    HazMat Fee

    An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

    The shipment is processed through FedEx Ground under the Limited Quantity option.

    Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

    If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

Tachysterol 3 is a photoreactive sterol derivative featuring a conjugated triene system that undergoes efficient [6+4] cycloaddition upon UV irradiation. This structural motif enables rapid, regioselective ring formation in synthetic photochemistry workflows. The compound exhibits enhanced stability under ambient conditions and integrates seamlessly into complex molecular scaffolds during cascade reactions.

Application

Tachysterol 3 serves as a key intermediate in the synthesis of vitamin D analogs, exhibiting well-documented photochemical reactivity under UV irradiation to form biologically active derivatives. Its conjugated triene system enables predictable isomerization pathways and functions reliably in standard steroid-based transformations. The compound demonstrates sufficient bench stability for routine handling and purification, making it a practical choice for medicinal chemistry workflows involving secosteroid scaffold construction.
